Project version table for ECP

Hello Gurus,

im in search of table in which ECP data of different Project versions is stored.

Im using PRPS, CKHS, CKIS tables to get detailed line items of easy cost planning.

I also know VSPRPS_CN table, which stores the version ID and other information, but i cant find anywhere the versioned line items.

Lets say ive created a project, then generated V.01, afterwards V.02, V.03, .. V.NM.

Maybe you know where are the data stored, or maybe some advice where to look for, cause im out of ideas

P.S. ive used trace tools but nohelp from them either.

Best regards

Laurynas Prikockis
